The apps

What I'm building.

GradeKey

Every point. Every grade. Instantly.

iPhone & iPad · Education

GradeKey turns any assignment's total point value into a complete grade conversion table — every possible score, percentage, and letter grade, generated the moment you type the total. Built for teachers who are tired of rebuilding the same spreadsheet before every quiz.

Instant conversion tables
Look up by points off, points earned, or grade %
8 grading scales plus custom tiers
Extra credit past 100%
PDF & CSV export
Free iCloud sync

Grocerly

Your staples, remembered.

iPhone, iPad & Mac · Shopping

Grocerly organizes your shopping by the stores you actually go to. Mark something purchased and it disappears — then quietly comes back on its own schedule, so the things you buy every week never need re-adding.

Recurring items that resurface on schedule
Organized by store
Grocery Run — one combined shopping view
Household sharing over iCloud
iPhone, iPad & Mac

NotionShare

Save from your Mac to Notion.

Mac · Productivity

Save from the macOS Share Sheet
Search Notion pages and databases
Extract clean articles and source details
Pin favorite Quick Access destinations

More on the way

New apps are in progress. Follow along or say hello — I'm always happy to hear what would actually be useful.

About

One person, start to finish.

IntraPixel is Hernan Rosario. I teach, and I build the software I wished existed while teaching. Every app here is designed, built, and supported by me.

Designed & built solo

Built for each platform

Small, fast & focused

How I build

Three principles.

Do one thing well

Each app solves a single problem completely instead of ten problems partially.

Made to feel at home

Thoughtfully built for the platform — whether that's mobile, desktop, or the web. Fast, focused, and easy to use.

Supported by a person

Bug reports and feature ideas go straight to the person who built the app — not a queue. I read every one.
